Maybe we’re a little bitter because we held on to our pumpkin futures well into November, but we’ve got to respect [Nick]‘s stock ticker ornament. It’s an Internet-connected Christmas ornament that queries stock prices and displays the change with an RGB LED.
The build uses a Propeller Platform USB and the Propeller E-Net Module to pull stock quotes down from Google. With the attached source, selecting any traded company is easy enough; all that’s needed is to select a company is changing a line in the code. The Propeller pulls the quote every 30 seconds during the trading day, and parses it into a ‘percent changed’ format. The ornament glows red if the change is more than a 4% negative change, green for within 0.2% of open, and blue if more than a 4% positive change.
[Nick] is more of a ‘set it and forget it’ investor, so this ornament is a handy, passive way to keep an eye on his investments. Check out the demo vid after the break.
